I was using system.tag.configure to alter some existing UDT tags to a different type based on a dataset that represented the tag folder and tag quantity. Most of the tags were created with no issue, however there were somewhere between 2-5 in each group of about 45 tags that were unable to be created and had a quality in the returned status list of Error\_Exception. The error for one of the tag edits from the logs and the script are both pasted below. This is using b2019031502. Once I deleted the offending tags and ran the script with the tags nonexistent the tags were created fine. Script: ```auto pcsDataset = system.tag.readBlocking(['[NC21-SITE]Configuration/Device Quantities/PCS/Inverters'])[0].value rowCount = pcsDataset.getRowCount() for row in range(rowCount): pcsNum = pcsDataset.getValueAt(row,'PCS') invQty = pcsDataset.getValueAt(row,'Inverter Quantity') print 'PCS =',pcsNum print 'Inverter Quantity -',invQty basePath = '[NC21-SITE]PCSs/PCS '+str(pcsNum)+'/Inverters' tagList = [] for invNum in range(1,invQty+1): deviceName = 'PCS '+str(pcsNum)+' Smart Logger' offset = ((invNum - 1) * 25) + 51000 parameters = {'InverterID':invNum, 'Offset':offset, 'DeviceName':deviceName, 'UnitId':'1'} tagName = 'Inverter '+str(invNum) tagType = 'UdtInstance' typeID = 'Inverters/INV SMRT LOG V2' tagDict = {'name':tagName, 'accessRights':'Read_Write', 'tagType':tagType, 'typeID':typeID, 'parameters':parameters} tagList.append(tagDict) smartLoggerDeviceName = 'PCS '+str(pcsNum)+' Smart Logger' totalInverters = invQty smartLoggerUnitID = '1' smartLoggerParameters = {'DeviceName':smartLoggerDeviceName, 'TotalInverters':totalInverters, 'UnitId':smartLoggerUnitID} smartLoggerTagDict = {'name':'Smart Logger', 'tagType':'UdtInstance', 'typeId':'Smart Logger/SMRT LOG V2', 'accessRights':'Read_Write', 'parameters':smartLoggerParameters} tagList.append(smartLoggerTagDict) print basePath print len(tagList) system.tag.configure(basePath,tagList) ``` Error from gateway logs: ```auto provider 19Mar2019 14:35:02 Error processing edit for tag path '[NC21-SITE]PCSs/PCS 8/Inverters/Inverter 7': Error_Exception

Thanks for reporting this. I think we’ve tracked it down, probably won’t get merged in tonight, but hopefully by tomorrow night. ---
